The document summarizes a study that evaluated 36 distance learning courses with approximately 23,600 students to analyze the impact of computer-mediated interaction on distance education. The courses were grouped based on their level of interaction and integration of materials. The results showed lower completion rates in mathematics, science, and technology courses compared to higher completion rates in social care, health, arts, and social sciences courses. The conclusion is that comparative studies of traditional methods are still needed as the effectiveness of distance learning sometimes works and sometimes does not.
